Dexpramipexole (also known as KNS-760704/R-pramipexole) was originally developed by University of Virginia researchers to treat Amyotrophic Lateral Sclerosis and then was licensed to global biotechnology company Biogen Idec for further development. However, on phase III clinical trial the study of this drug was discontinued. Biogen said the drug neither slowed the loss of muscle function nor prolonged the lives of patients with ALS, often called Lou Gehrig’s disease. Nor did it show any efficacy in secondary endpoints of the clinical trial, or work in any sub-group of patients—about a big a failure as a company could have a Phase III trial. In addition, was discovered, that dexpramipexole was able to bind to beta-subunit of the mitochondrial F1/FO ATP synthase complex and increased its activity, thus reduced ischemic brain injury. These findings, together with the excellent brain penetration and favorable safety profile in humans, make dexpramipexole a drug with realistic translational potential for the treatment of stroke.

Sample Use Guides
It was found that dexpramipexole (DEX) binds to the oligomycin sensitivity–conferring protein (OSCP) and b-subunits of the F1/FO ATP synthase, suggesting that it may indirectly inhibit the c-subunit (mPTP) pore by producing a conformational change in complex V that places F1 over the pore, inhibiting its conductance. The human open reading frame constructs for α, β, b, c, δ, d, ε, γ, and oligomycin sensitivity–conferring protein (OSCP) ATP synthase subunits were used. 293T cells were transfected with the above constructs. On day 3 post-transfection, the cells were lysed. The proteins were eluted from a portion of the samples, and the presence of the proteins on the beads was verified by immunoblot analysis, using mouse anti-Myc antibodies. The protein-bound beads were incubated in the presence of [14C]DEX (range of concentration was: 1-10 uM).
